Abstract:

This study scrutinizes climate profile and appraises its social and economic values in reducing climate-related impacts on Agricultural product over Adama district. The study used CHIRPS data, daily, decadal, monthly, seasonal and annual station data used from NMA. Statistical methods applied to generate recent climate characteristics and climate events of district and secondary data from published and unpublished sources, and systematically analyzes the data both using qualitative and quantitative analysis. The result showed that the trend of gradual, extreme events and meteorological drought increased agriculture vulnerability in the study area. According to the 38 years (1981-2019) CHRIPS Rainfall estimates from rain gauge and satellite observations/CHIRPS Blended with station data/ and the 31 years meteorological gauged station data (NMA). The highest Annual and seasonal average Maximum Temperature recorded over district is 29.7 0c & 31.00c during 2011 and lowest is 13.10c & 10.40c respectively. The maximum temperature trend has been increasing but the minimum temperature has been decreasing which shows the climate changes over district. Averagely season starts during May while the season starts at minimum period of April. The season ends averagely at the end of September and the minimum ends at October. Averagely the LGP of district is more than 4 months and minimum and maximum is 3 and 4 months respectively. Overall, the results of Belg and Annual rainfall trend have been decreasing while Bega and Kiremt seasonal rainfall amount has been increasing. The driest year over district was happened during El-Nino year 1987, 2002 & 2015 in contrast the wettest year of district during La-Nina Year 1999, 2000 & 1998. The coldest year and the warmest were during 2014 and 2017 correspondingly. Kiremt and Belg season rainfall variability increases in the recent decade.
